2. INTRODUCTION
Noise Control in Buildings: Why It Matters
• Improved Comfort and Well-being
• Enhanced Productivity and Concentration
• Better Sleep Quality
• Reduced Health Risks

3. ⚬ Imagine sound as a ripple traveling through a medium, like air or
water. This ripple is a variation in pressure compared to the
surrounding environment.
Understanding Sound
The Building Blocks of Noise
Sound as a Pressure Wave
Key Characteristics of Sound
• Frequency
• Amplitude
• Wavelength

4. The Impact of Noise on Occupants
Noise pollution within buildings isn't just a minor inconvenience – it can
significantly impact the well-being of those who use the space.
• Reduced Productivity and Concentration
• Impaired Communication and Collaboration
• Disrupted Sleep Quality and Relaxation
• Potential Hearing Health Problems
• Increased Stress and Anxiety Levels

5. PARAMETERS
Building materials are generally
rated by their noise reduction
coefficient(NRC).
Sound Transmission Class (or
STC) is an integer rating of
how well a building partition
attenuates airborne sound.

6. WAYS TO CONTROL
●Three BASIC ways to control noise
1. Replace the sound source with a quieter one.
2. Block the sound with a solid, heavy material that resists the
transmission of sound waves.
3. Absorb the sound with a light, porous material that soaks up
sound waves.
Acoustical design issues for buildings include site noise considerations,
control of noise transfer, establishing noise standards, room acoustics
considerations, sound isolation, vibration control and audio/visual
considerations

7. METHODS
SOUND INSULATION
• The surface can absorb sound
instead of reflecting it.
• Good sound-absorbing materials
are carpet, foam, padding, and
fiberglass insulation.
• Method: Room acoustics
• Through sound barrier
transmission, sound is reduced.
• By increasing wall thickness
and isolating one side of
construction from the other.
• Methods: Wall construction,
Floor planning, space planning.

8. ROOM ACOUSTICS
ROOM ACOUSTICS
• We receive direct and reflected sound in a room.
• Unwanted background noise is due to a high level
of reflected sound in poor acoustical rooms.
• To achieve acceptable acoustic characteristics
various points are taken into consideration:
1. location and extent of sound-absorbing materials
2. reduction of reverberation and speech interference
3. Shape of room(for libraries)

11. WALL CONSTRUCTION
The standard partition is a single
stud wall and one layer of gypsum
board on each side, the acoustic
performance can be improved by
using light gauge metals instead of
wood studs.
STC (Sound transmission class) is a
standard parameter to compare the
performance of different
construction materials

12. SPACE PLANNING
Space planning involves organizing spaces
to avoid adverse adjacencies of noisy
equipment like mechanical equipment and
electrical transformers with quiet spaces.
It can be the most cost-effective noise
control technique.
FLOATING FLOOR CONSTRUCTION

13. •Noise is becoming a very big problem day to day it is degrading our
health and ecological balance as well. One cannot remain untouched
by this aspect of day-to-day issues.
•By introducing noise control in buildings we can create less noisy
residential and other constructions. As sound travels directly and
through reflections, so to improve sound quality reflections should be
minimized.
